Answer:

the download cost for a song is $1 and $11 for a movie

Step-by-step explanation:

According to the questions, the following equations are as follows:

Let us assume the song be x

And, the movies be y

So,

20x + 13y = $163.........(i)

13x + 13y = $156........(ii)

Now solve substract second equation from the first equation

7x = $7

x = $1

And the y value is

20 + 13y = $163

13y = $163 - $20

13y = $143

y = $11

Hence, the download cost for a song is $1 and $11 for a movie

Answer:

60

Step-by-step explanation:

The required number is 60.

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now the given expression is,

4.5 is 7.5%

Let x be the number.

Therefore, 7.5% of x is 4.5

⇒ 7.5% of x = 4.5

⇒ 7.5% * x = 4.5

⇒ 7.5/100* x = 4.5

⇒0.075 x = 4.5

Dividing both side by 0.075 we get,

x = 4.5 / 0.075

Solving we get,

x = 60

this is the required number.

Thus,the required number is 60.

In mathematics, proportions refer to the equality of two ratios. A ratio is a comparison of two quantities, typically expressed as a fraction. When two ratios are equal to each other, they form a proportion.

A proportion can be written in the form:

a/b = c/d

Here, "a" and "b" are the terms of the first ratio, and "c" and "d" are the terms of the second ratio. The proportions state that the ratio of "a" to "b" is equal to the ratio of "c" to "d".
